DESCRIPTION
Refrigeration Cycle
REFRIGERANT FLOW
The refrigerant flowisinthe standard pattern.Refrigerant flowsthrough thecompressor, condenser,
liquid tank,evaporator andback tothe compressor.
The refrigerant evaporation throughtheevaporator coiliscontrolled byan externally equalizedexpan-
sion valve, located insidetheevaporator case.
FREEZE PROTECTION
The compressor cyclesonand offtomaintain theevaporator temperature withinaspecified range.When
the evaporator coiltemperature fallsbelow aspecified point,thethermo controlamplifier interrupts the
compressor operation.Whentheevaporator coiltemperature risesabove thespecification, thethermo
control amplifier allowscompressor operation.
REFRIGERANT SYSTEMPROTECTION
Dual-pressure switch
The dual-pressure switchislocated onthe liquid tank.Ifthe system pressure risesorfalls outof
specifications, theswitch openstointerrupt compressor clutchoperation.
Fusible plug
Open attemperature above105°C(221°F), thereby discharging refrigeranttothe atmosphere. Ifthis plug
is melted andopened, checktherefrigerant lineand replace liquidtank.
